1.AGV

BETTER ANSWER:

Computer Integrated Manufacturing by N. Venkateshwaran (1 Jan 2010)

SF 227



OLD ANSWER:

AGV (Automated guided vehicles) (Automation)

Automated guided vehicles can move workpieces a great distance,
but they lack the speed found in both robot and transfer
lines. Yet because of their ability to be programmed to different
routes, they are more flexible than transfer lines.AGV
Automated guided vehicles (which are are the lastest development in material movement in plants) operate automatically along pathways which in-floor wiring (or tapes for optical scanning) without operator intervention. This transport system has high flexibility and is capable of random delivery to different workstations.

OLD ANSWER: AGV

An automated guided vehicle system (AGVS) is a material handling system that uses independently operated, self-propelled vehicles guided along defined pathways. The vehicles
arc powered by on-board batteries that allow many hours of operation (8-16 hr is typical) between recharging. A distinguishing feature of an AGVS. compared to rail guided vehicle systems and most conveyor systems, is that the pathways are unobtrusive, An AOVS is appropriate where different materials are rnovco from various load points to various unload points. An AGVS is therefore suitable for automating material handling in batch production and mixed model production. The first AGV was operated in 1954.

2. BED OF NAILS DEVICE

BETTER:





Building a Successful Board-Test Strategy (Test and Measurement Series) by Stephen Scheiber (9 Nov 2001) Page 70-71





OLD:

Bed-of-Nails Device:

This fixture consists of a series of air-actuated pins that conform to the shape of the external surfaces of the part. Each pin moves as necessary to conform to the shape at its point of contact with the part. The pins are then mechanically locked against the part. The device is compact, has high stiffness and is reconfigurable.

3. POWERHEAD PRODUCTION UNITS

BETTER
:


Powerhead production units which consist of a base with feed mechanism, a drive unit (power spindle), and several interchangeable attachments, so that various operations (drilling, tapping, turning, milling, etc) can be carried out according to need.

New York u.a. : McGraw-Hill, 1977. Introduction to manufacturing processes,  John A Schey 



OLD

Powerhead production unit

Consisting of a frame or bed, electric drive motors, gearboxes , and tool spindles, these units are self-contained. Their components are available commercially in various standard sizes and capacities. Because of this inherent modularity, they easily can be regrouped for producing a different part and thus have some adaptability and flexibility. (Kalpakjian S., Schmid S.R., Manufacturing engineering and technology, 5th Edition, page 1150)

4. INTERPOLATION

BETTER: 


Computer Aided Manufacturing: For Anna University, Tamil Nadu by C. Elanchezhian, Sunder T. Selwyn and Shanmuga Sundar (30 Dec 2005)






OLD:
Interpolation- Movement along the path occurs incrementally by one of severall basic methods. In all interpolations, the path controlled is that of the center of rotation of the tool. Compensation for different types of tools, for different diameters of tools, or for tool wear during machining can be made in the NC program. There are 3 types:
Linear interpolation
. Circular interpolation
. Parabolic interpolation
(Kalpakjian S., Schmid S.R., Manufacturing engineering and technology, p. 1158)
